now he's behind bars and the fbi is joining the investigation. lisa sylvester here, this is one of those stories that makes you go, how did this happen. >> yeah, this is truly one of those pretty wild stories here. he was actually a ticketed passenger, so he didn't breach security. but let's just say when he didn't like his seat assignment, he tried to pass himself off as a pilot. in the movie "catch me if you can" a smooth-talking leonardo dicaprio flies around the world posing as a pilot. philippe jernnard thought he could pull something off similar. jernnard, a retired winemaker, was traveling from france headed to west palm beach and was on a layover in philadelphia. he was dressedn a white button-down shirt with a airfrance logo over the pocket. jernnard went to the gate and tried to get his seat upgraded from coach. but an agent said business class was already full and couldn't accommodate his request. that's when authorities say he boarded the plane and went straight to the cockpit, and sat behind the pilot in what's known as a jump seat.
